Benign neoplasm of unspecified renal pelvis

This diagnosis code signifies the presence of a non-cancerous growth originating within the renal pelvis, the funnel-shaped part of the kidney that collects urine. It indicates that the specific side (left or right) where the neoplasm is located has not been documented or determined.

Use this code when diagnostic imaging (e.g., CT scan, MRI, ultrasound) or biopsy confirms a benign neoplasm of the renal pelvis, but the laterality is not specified in the medical record. This code is appropriate when the physician's documentation explicitly states "benign neoplasm of renal pelvis, unspecified side" or similar.

• Avoid using this code if laterality (left or right) is documented; instead, select the more specific D30.11 (right) or D30.12 (left).
• Ensure the pathology report or imaging interpretation clearly states "benign" to differentiate from malignant neoplasms of the renal pelvis (C65.-).
• Do not use this code for benign neoplasms of the kidney parenchyma (D30.0-) or ureter (D30.2-).
